Thanks.

To perform a mouse click:
[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
public static extern void mouse_event(long dwFlags, long dx, long dy, long cButtons, long dwExtraInfo);
private const int MOUSEEVENTF_LEFTDOWN = 0x02;
private const int MOUSEEVENTF_LEFTUP = 0x04;
private const int MOUSEEVENTF_RIGHTDOWN = 0x08;
private const int MOUSEEVENTF_RIGHTUP = 0x10;
public static void DoMouseClick()
{
mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);
}
To move the cursor where you want:
[DllImport("user32.dll")]
static extern bool SetCursorPos(int X, int Y);
public static void MoveCursorToPoint(int x, int y)
{
SetCursorPos(x, y);
}
If it's right on a button, you can use
button1.PerformClick();
Otherwise, you can check out this MSDN article which discusses simulating mouse (and keyboard) input.
Additionally, this project may be able to help you out as well. Under the covers, it uses SendInput.
Use the Win32 API to send input.
Update:
Since I no longer work with Win32 API, I will not update this answer to be correct when the platform changes or websites become unavailable. Since this answer doesn't even conform to Stackoverflow standards (does not contain the answer itself, but rather a link to an external, now defunct resource), there's no point giving it any points or spending any more time on it.
Instead, take a look at this question on Stackoverflow, which I think is a duplicate:
